DETAILED DESCRIPTION

The following description is made for the purpose of illustrating the general principles of the invention and is not meant to limit the inventive concepts claimed herein. Further, particular features described herein can be used in combination with other described features in each of the various possible combinations and permutations. Unless otherwise specifically defined herein, all terms are to be given their broadest possible interpretation including meanings implied from the specification as well as meanings understood by those skilled in the art and/or as defined in dictionaries, treatises, etc.

The description may disclose several preferred embodiments of kneepad caps, as well as operation and/or component parts thereof. While the following description will be described in terms of kneepad caps and kneepads for clarity and to place the invention in context, it should be kept in mind that the teachings herein may have broad application to all types of systems, devices and applications.

One embodiment of the invention provides a kneepad cap including an upper portion with a curved front portion with a first curve radius. A center portion is attached to the upper portion. The center portion includes a first platform portion and curved side portions having a second curve radius. A lower portion is attached to the center portion. The lower portion includes a curved back portion having a third curve radius. The stable platform portion of the kneepad cap provides a user of a kneepad including the kneepad cap embodiments to maintain their position via the flat platform being in contact with a surface (e.g., the ground). The front curved portion allows a user of the kneepad cap embodiments to rotate or rock forward as the front curved portion rotates the user forward, which expands the forward working distance of the user without the user having to reposition to another position on the surface.

FIG. 1 illustrates a perspective view of one embodiment of a kneepad system 100 including kneepad cap 105 and a kneepad 120 including attachment, cushioning and strapping elements. In one embodiment of the invention, the kneepad cap 105 includes an upper portion 110, a center portion including sections 130 and 140 and a lower portion 150. In one embodiment of the invention, the kneepad cap 105 is surrounded by a first perimeter portion 106 and a second perimeter portion 108, wherein a molded groove or channel 107 is formed. In one example, the kneepad cap is attached to the kneepad 120 via stitching within the channel 107. The molded groove or channel 107 where the stitching attaches the kneepad cap 105 to an outer surface of kneepad 120 protects the stitching from abrasion for longer product life.

In one embodiment of the invention, the upper portion 110 includes a front curved portion having a larger radius of curvature than the bottom section of the lower portion 150 as well as each of the sides of the first section 130 and the second section 140. In one embodiment of the invention, the kneepad cap 105 is made of molded polyurethane. In other embodiments of the invention, the kneepad cap 105 may be made of other similar materials to polyurethane. In one example, gel materials may be employed along with the kneepad cap 105 for additional comfort. In one embodiment of the invention, the upper portion 110, the first section 130, the second section 140 and the lower portion 150 are integrally molded as a single device.

FIG. 2 illustrates a front view of the kneepad cap 105 according to one embodiment of the invention. In one embodiment of the invention, the curve of the front curved portion of the upper portion 110 ranges from 40-75 degrees; the curve of the sides 235 of the first section 130, the sides 245 of the second section 140, and the sides 255 of the lower portion 150 ranges from 20-30 degrees; and the curve of the bottom of the lower portion 150 ranges from 20-35 degrees. In one example, the front curved portion of the upper portion 110 provides the kneepad cap 105 to be able to rock or rotate forward and back similar to the movement of the legs of a rocking chair. In one example, the first section 130, the second section 140 and the lower portion 150 each have a platform (e.g., flat or near flat) portion that provides stability to a user when pressed against a ground surface. In one example, the upper portion 110 includes a platform portion 205.

In one embodiment of the invention, the first section 130 includes a recessed portion 210. In one example, the recessed portion 210 may include an applied emblem, logo, etc. In another example, the recessed portion 210 may include a radio frequency identification (RFID) element used for retail purposes (e.g., security, checkout, inventory, etc.). In one embodiment of the invention, a groove or channel 260 is formed between the upper portion 110 and the first section 130.

In one embodiment of the invention, a groove or channel 265 is formed between the second section 140 and the first section 130. In one embodiment of the invention, a groove or channel 270 is formed between the lower portion 150 and the second section 140. In one example, the channels 260, 265 and 27 provide additional flexibility for the kneepad cap 105 when forced against non planar surfaces or when a user wearing the kneepad cap 105 with a kneepad 120 bends by allowing for flexing of the upper portion 110, first section 1130, second section 140 and lower portion 150.

FIG. 3 illustrates a rear view of the kneepad cap 105 according to one embodiment of the invention. In one embodiment of the invention, the upper portion 110 includes structural support joints 310 and 311 that are formed during a molding process. In one embodiment of the invention, the first section 130 includes formed structural support joints 330 and 335, and the second section 140 includes formed structural support joints 340 and 345, where the structural support joints 330, 335, 340 and 345 are formed during a molding process. In one embodiment of the invention, the lower portion 150 includes structural support joints 350 and 355 that are formed during a molding process. In one example, the structural support joints 310, 330, 340, 350 and 355 add strength to the kneepad cap 105. In one example, the rear portion 312 of the recessed portion 210 extends into an opening in the rear of the kneepad cap 105.

FIG. 4 illustrates a side view of the kneepad cap 105 according to one embodiment of the invention. As illustrated, the upper portion 110 has a larger radius of curvature than that of the sides of the first section 130, the sides of the second section 140 and the sides and back of the lower portion 150.

FIG. 5 illustrates a side cut-away view of the kneepad cap 105 shown in a stabile state on an example surface 505 (e.g., ground, a planar surface, etc.). As shown, the surface 510 of the upper portion 110 is raised off of the example surface 505 due to the radius of curvature of the upper portion 110. The surface 530 of the first section 130, the surface 540 of the second section 140 and the surface 550 of the lower portion 150 are parallel with the example surface 505. In this stable state of use of the kneepad cap 105, stability is achieved based on the surfaces 530, 540 and 550 being in contact with the example surface 505 due to their respective platform portions.

FIG. 6 illustrates a side cut-away view of the kneepad cap 105 shown in a forward rocked state on an example surface 505 rocked/rotated in the direction of arrow 610. IN the forward rocked state, the user of a kneepad including the kneepad cap 105 may rock forward to extend the distance for which the user can complete tasks. The rocking ability of the kneepad cap 105 may also provide an added comfort in mobility for users. Combined the stability state of the platform portions of the kneepad cap 105 combined with the rocking mobility of the kneepad cap 105 provides multiple functionality for the users wearing a kneepad with the kneepad cap 105 embodiments.
